HYSPLIT On-line Workshop

Hosted by NOAA's Air Resources Laboratory

Note, there will be no more in-person or live video-conferenced HYSPLIT Workshops held as has been done in the past. Instead, during a four-week period, an agenda will guide the user on their own through most sections of the current online Basic Tutorial materials with each week focusing on several sections (such as installation, meteorology, trajectories, dispersion, etc). This will allow the user to learn the materials at their own pace and time.

During the week users will be able to submit questions on the sections being studied to the HYSPLIT Forum that will be answered by HYSPLIT experts. On the following Monday a live, 1-hour, video session will be held at 4 pm EDT (2000 UTC) and, on Tuesday, another identical session will be held at 9 am EDT (1300 UTC). During these sessions, the instructor will review the questions that were received during the week and, if time permits, allow users to ask new questions on the material covered in that week's session.

2019 Self-paced Agenda

Information on the 2020 HYSPLIT workshop will be posted here in the Spring of 2020.

If your organization is interested in hosting a workshop, please send an email to with details of your interest. We are a very small laboratory, but we may be able to arrange one or two individual workshops per year.

Training materials

All the materials that will be used in the training are available online and are designed to be self-pacing with all the graphics and examples needed. The tutorial is available at:

Model Download

The current Mac and PC trial versions (v927 and v927 respectively) of the model will be used for workshop and is included in the "programs" directory of the Tutorial. The PC registered version or either versions of the MAC can also be used but the results may not always match the tutorial results because they are a later version of the model. The PC trial version of the model can be downloaded from:
